The brain is our most important organ and perhaps the least well

understood. Our brain is the “command station” for our body. It controls

what we think, what we feel and what we do. It is the home of our

emotions and personality. It makes sense of our experiences.

But how does the brain work? The truth is that, after decades of research,

scientists and doctors are only now beginning to figure out that question.

We know that different types of cells in the brain work together to form

certain areas which have specialist roles in memory, vision and logical

thinking. We also know that hormones and chemicals influence our brain

and our emotions and that we are very sensitive to changes in their levels.

We know that the different brain areas mature at different stages and are

connected by tracts, rather like railway lines, which can sometimes go

astray and lead to illnesses. And finally we know that by looking in the

blood we can find clues, called biomarkers, which may ultimately help us

to understand and predict brain disorders.

Through this book we want to help everyone to understand the workings

of the brain through pictures and cartoons. If you would like to learn
